Hi.

All the images smaller than the MEDIUM size setting aren't displayed, because they're not being created/generated.

In Configuration > Options > Photo sizes, MEDIUM size is set to 792 x 594 pixels.
Here, only the default "Square", "Thumbnail" and "Medium" are selected.

In the thumbnails page (example: https://www.cameltrophyportugal.com/fot … ategory/23) all images are created and displayed, and their source is "*-cu_e260x180.jpg". They all link to "picture.php?/<PICTURE-ID>/category/<CATEGORY-ID>". All this seems to be correct.

However, when I click one of the thumbnails, there are 2 different situations:

1) original image is smaller than MEDIUM size (792 x 594 pixels)
example URL: https://www.cameltrophyportugal.com/fot … ategory/23
Original image size (same as saved in "width" and "height" fields in the _images DB table): 552 x 457
Result: image isn't displayed and the source HTML is "<img src="action.php?id=371&part=e" width="552" height="457" alt="CTPB_CT80_006.jpg">"

2) original image is bigger than MEDIUM size (792 x 594 pixels)
example URL: https://www.cameltrophyportugal.com/fot … ategory/23
Original image size (same as saved in "width" and "height" fields in the _images DB table): 475 x 864
Result: image isn't displayed and the source HTML is "<img src="_data/i/galleries/edicoes/CT80_CTPB/CTPB_CT80_007-me.jpg" width="326" height="594" alt="CTPB_CT80_007.jpg">"
The previous example is for portrait/vertical images, but landscape/horizontal images work fine, as well.

If I manually generate a "-me.jpg" file, it still isn't loaded.
Example URL: https://www.cameltrophyportugal.com/fot … ategory/23
Manually created "-me.jpg" image file URL: https://www.cameltrophyportugal.com/fot … 001-me.jpg

The only way for the manually created "-me.jpg" image file to be loaded is if I change the "width" or "height" fields in the _images DB table, to values higher than the MEDIUM size setting, like 793 for "width" or 595 for "height".

However, this is not a solution because if I perform a synchronisation all values in the DB will be updated to the correct ones.

Additional information:
a) The template being used is "SimpleNG" version 3.2.7 (latest available). The same behaviour existed in version 3.2.5.
b) In the "Smart Pocket" template version 11.5.0, there is a difference: in the thumbnails page, only the "correct" images are displayed; the images without "-me.jpg" image file aren't displayed in the thumbnails page (and - of course - the image isn't loaded when the thumbnial is clicked to open the image).

Do you have any idea on how to correct this issue, before I wipe everything and start over?

Thanks!
